We are offering silico manganese. Silico manganese (simn), a ferroalloy with high contents of manganese and silicon, is made by heating a mixture of the oxides manganese oxide (mno2), silicon dioxide (sio2), and iron oxide (fe2o3), with carbon in a furnace. They undergo a thermal decomposition reaction. It is used as a deoxidizer and an alloying element in steel. The standard grade silico manganese contains 14 to 16% of silicon, 65 to 68% of manganese and 2% of carbon. The low carbon grade simn has carbon levels from 0.05 to
